In order to treat her younger brother's illness, the heroine was forced to accept a ghost marriage and married a wealthy young man from a hundred years ago. Her husband is a powerful ghost sleeping in the ancient house and cannot appear during the day. In order to better "take care" of her, the ghostly husband forcibly possessed his twin descendants - a gloomy family head with disabled legs who also lived in the ancient house. During the day, the head of the house was cold and mean to her, making things difficult for her at every turn; at night, the head of the house, who was possessed by her husband, showed morbid obsession and lust for her. The heroine gradually cannot tell whether the person she falls in love with (or is afraid of) is the living person or the dead ghost. When the resentful spirit found out that the head of the family had an unwanted affection for the heroine during the day, he appeared in the mirror and asked his descendants: "Little guy, is it nice to occupy my bride during the day?" The conflict escalated from a supernatural incident in an ancient house to a terrifying frenzy in which the entire city was involved in the night walk of a hundred ghosts.
